I found this monitor in hard rubbish. The image quality is pretty rubbish, and it has a yellow tint. Native resolution is 1280×1024. As a second monitor it's fine for me!

xrandr doesn't recognise it so well, so I had to:

1. cvt 1280 1024 to get the 'modeline'
2. xrandr –newmode “1280x1024_60.00” 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync Everything after –newmode is grabbed from cvt.
3. xrandr –addmode DisplayPort-0 1280x1024_60.00 Yeah, x thinks this VGA port is a DisplayPort :/

Later edit: decided to move the config. to xorg.conf to I don't have to run the commands each time I start:

Section "Monitor"
	Identifier	"DisplayPort-0"		# NB: Actually VGA
	Modeline	"1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync
	Option		"RightOf" "HDMI-A-2"
EndSection

That goes in /etc/X11/xorg.conf.d/, and needs to be owned by your root user.

NB: Option “RightOf” “HDMI-A-2” is referring to my other monitor (which I also set-up in this file, just to make sure it's set to be the primary monitor), change (or just remove the whole Option line) accordingly.
